I was testing out my new automotive scanner on our 2018 Mazda 6, and noticed something odd. When poking around in the driver side footwell to locate the OBDII connector I was surprised to find...empty space! Looking up under the dash reveals a big cavernous area devoid of anything. Most of my other vehicles have this space crammed full of wiring, ducting, and all manner of black boxes. Seems the Japanese engineers at Mazda have truly perfected miniaturization or located everything elsewhere.
